Tritium is an isotope of hydrogen whose nucleus Triton contains 2 neutrons and 1 proton. Free neutron decay into `p+bare+barv`. If one of the neutrons in Triton decays. It would transform into `He^3` nucleus. This does not happen. This is because.

A

(a) triton energy is less than that of a `He^3` nucleus.

B

(b) the electron created in the beta decay process cannot remain in the nucleus.

C

(c) both the neutrons in triton have to decay simultaneously resulting in a nucleus with 3 protons, which is not a `He^3` nucleus.

D

(d) because free neutrons decay due to external perturbations which is absent in a trition nucleus.

Bohr's model of hydrogen atom In order to explain the stability of atom and its line spectra, Bohr gave a set of postulates: An electron in an atom revolves in certain circular orbit around the nucleus. These are the orbits for which mvr=(nh)/(2pi) In these allowed orbits, the electron does not radiate energy. When an electron jumps from higher energy level E_(n_2) to lower energy orbit E_(n_1) , radiation is emittd and frequency of emitted electron is given by v=(E_(n_2)-E_(n_1))/h . Further the radius of the n^(th) orbit of hydrogen atom is r=(n^2h^24piepsilon_0)/(4pi^2me^2) and energy of the n^(th) orbit is given by E_n=-13.6/n^2 eV . What would happen, if the electron in an atom is stationary?

Deutron is a bound state of a nuetron and a proton with a binding energy B=2.2 MeV. A gamma-rays of energy E is aimed at a deuteron nucleus to try to break it into a (neutron+proton) such that the n and p move in the direction of the incident gamma-rays . If E=B, show that this cannot happen. Hence calculate how much bigger than B must E be for a such a process to happen.

The question given below consist of an assertion (A) and a reason ( R). Use the following key to choose the appropriate answer to these questions from the codes (a), (b), ( c) and (d) given below: (a) Both A and R are true and R is the correct explanation of A. (b) Both A and R are true but R is NOT the correct explanation of A. (c) A is true but R is false. (d) A is false and R is also false. Assertion: Nucleus of the atom does not contain electrons, yet it emits beta -particles in the form of electrons. Reason: In the nucleus, protons and neutrons exchange mesons frequently.

Nuclei with magic no. of proton Z=2, 8,20,28,50,52 and magic no. of neutrons N=2,8,20,28,50,82 and 126 are found to be very stable. Verify this by the calculating the proton separation energy S_p for "^120Sn(Z=50) and "^121Sb=(Z=51) . The proton separation energy for a nuclide is the minimum energy required to separate the least rightly bound proton from a nucleus of that nuclide. It is given by S_p=(M_(z-1,N)+M_H-M_(Z,N))c^2 Given "^119ln=118.9058u , "^120Sn=119.902199u , "^121Sb=120.903824u , "^1H=1.0078252u .

Consider the decay of the free neutron at rest: n = p + e^- . Show that the two-body decay of this type must necessarily give an electron of fixed energy and, therefore, cannot account for the observed continuous energy distribution in the beta decay of a neutron or a nucleus.
